In this paper, a series of light-emitting copper(I) iodide inorganic–organic hybrid clusters has been synthesized, and they are 0D-Cu₂I₂(fmp)₄ (1, fmp = 3-fluoro-5-methyl-pyridine), 0D-Cu₂I₂(iq)₄ (2, iq = isoquinoline), 0D-Cu₂I₂(ni)₄ (3, ni = nicotinonitrile). They are all molecular clusters with Cu₂I₂ rhomboid dimer core which is the result of steric hindrance of organic ligands. The emissions of these compounds range from green to red in the solid state. The band gaps and emission energies of these compounds could be tuned by selecting different organic ligands. These compounds are solution processable and could be coated onto various substrates as luminescent inorganic–organic hybrid coating materials.

本文合成了一系列发光的碘化铜（I）无机-有机杂化簇，它们是0D-Cu ₂ I ₂（fmp）₄（1，fmp  = 3-fluoro-5-methyl-吡啶），0D-Cu ₂ I ₂（iq）₄（2，iq  =异喹啉），0D-Cu ₂ I ₂（ni）₄（3，ni  =烟腈）。它们都是具有Cu ₂ I _2的分子簇菱形二聚体核心是有机配体空间位阻的结果。固态时这些化合物的发射范围从绿色到红色。这些化合物的带隙和发射能可以通过选择不同的有机配体来调节。这些化合物是可溶液处理的，可以作为无机-有机杂化发光材料涂覆在各种基材上。
